. Tydén P, Engström G, Hansen O, Hedblad B, Janzon L (Malmö University Hospital, Lund University, Malmö, Sweden). Geographical pattern of female deaths from myocardial infarction in an urban population: fatal outcome out‐of‐hospital related to socio‐economic deprivation. J Intern Med 2001; 250: 201–207. Objective. This study of myocardial infarction (MI) amongst urban women has sought to assess whether there are differences in fatal outcome, in‐hospital respectively out‐of‐hospital, between residential areas defined in terms of socio‐economic circumstances. Design. Register‐based surveillance study 1986–95. Setting. Seventeen residential areas in the city of Malmö, Sweden. Subjects. Women 20–74 years of age. Main outcome measures. Differences in fatal outcome, in‐hospital respectively out‐of‐hospital, between residential areas were expressed in terms of age‐adjusted odds ratios (ORs), calculated by means of logistic regression. Socio‐economic circumstances in the areas were expressed in terms of a composite score. Results. Between residential areas there were marked and statistically significant differences in incidence (range 124–328/10 5 , P < 0.001, d.f.=16) and mortality (range 38–132/10 5 , P < 0.005, d.f.=16). Area rates of mortality covaried with incidence ( r =0.85, P < 0.001) and with odds ratios of fatal outcome out‐of‐hospital ( r =0.52, P =0.031) but not in‐hospital. The odds ratios of fatal outcome out‐of‐hospital decreased in a statistically significant stepwise fashion from areas in the lowest socio‐economic quintile (reference) to areas in the highest socio‐economic quintile (OR: 0.67, 95% CI: 0.48–0.94). There was no corresponding association with the odds ratios of fatal outcome in‐hospital. Conclusions. The high rate of mortality from MI amongst women in areas with deprived socio‐economic circumstances was related to deaths occurring out‐of‐hospital. In order to assess the preventive potential there is a need for further studies that may clarify to what extent the association with socio‐economic circumstances can be explained by other factors and conditions known to influence the probability of survival.
